WIFI not working!!! - Galaxy S II Q&A, Help & Troubleshooting

Hi guys,
I flashed my SGSII into the leaked 2.3.4 firmware and installed the CF-root based on the KF2. After that my WIFI does not work anymore. No matter what I tried the WIFI just refused to work. I tried to flash back to KF2 but to no avail. I am now at original firmware XXKF2. But strangely, my Kiesair can work. So I am guessing the problem is software based. Please help!!!
*edit* I reflashed 2.3.4 firmware and installed villainrom 2.0 exactly as pulser's forum page instructed. Still no luck. Please help!!

Please help!!

same here!
after 2.3.4 no more wifi (villain and litening). back to KE2 and from there with KIES to KF3.
still no wifi.

I lost wifi when i installed VillainRom 2.0 and the stock KG1 kernel, when chainfire released his CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4 i flashed that and wifi started working again. I'm a dumbo, i remember reading that VR only supports CW kernel, oh well, lesson learned

I see so you flashed the updated cf root after u installed villainrom? Or u redid everything again from reflashing stock KG1 then cfroot then villain rom?? I am more of a noob. What is CW kernel???

CW = ClockWork, have a look at this thread it should explain everything.
I'd imagine if you are using VillainRom 2.0, and you flash the CF-Root-SGS2_XX_OXA_KG1-v4.1-CWM4 kernel from the above thread (it's in post #4), your wifi should start working again like it did for me.

Did u use cwm to flash?? Or using odin to flash the .tar file??

I was too lazy to copy the file to the phone, so i put it in download mode and used Odin

Cool. Will update u when I tried. Thanks man. : )

its really weird that im back on full stock rom, unrooted and wifi still doesnt work.

OK no wifi, does that mean no icon? doesn't turn on? turns on but no aps listed? aps listed but cant connect? can connect but no data?
Need to be more descriptive when posting

Hi Deanwray, please forgive my lack of forum skills. : ) I can get the icon and iconnect to WIFI with all relevant parameters like subnet mask, DNS Server and IP address showing up on the status of the connection. I can transfer data through KIESAIR and I can tether through WIFI. But I can't surf the web nor use any application that needs a data connection. They will just try and try until they give up.
I just flashed 2.3.4 firmware and installed villainrom 2.0. I think that somewhere along the steps in installing the villainrom, I might have missed something. I will try to reflash the root kernel from chainfire and then try again.

I have the same problem with 2.3.4. Have already tried it with stock/litening 2.1. Is there a solution for this?

Hey guys, try mrxd's suggestion. I am on my way home to test out on my wifi. Didn't have the chance to connect to any wifi device the whole day!!! I tried mrxd's suggestion and flashed the root cf-root kernel after installing villainrom 2.0 using odin. Will post my findings once i get home. : )

Wad I did was to flash the KG1 cf-root kernel onto my GSII using Odin AFTER installing villainrom. Woo!!! Felt really good!!

Glad it worked for you

Because you need to reflash the darned ROM which you have screwed with the non-working patch. Read!
i even reflashed the ROM dude........bt same prob
plz gimme a link of ur kernel version
RoM n baseband
Well, flash a full stock ROM via KDZ and move on. When you have done some reading (which clearly hurts your brain), come back with some non-PEBKAC issues. While you have mismatch between your baseband and ROM, you have no GSM and data. It is written in the howto, but then again, too long and boring to read, huh?
Bye.
Hello ppl. I have flashed to new baseband w/ Cyanogenmod 9(lurpohip) and franco's newest kernel. I can call and send text messages, but data doesn't seem to work. Would appreciate help. I've gone through both how-to's pt. baseband LGMDP.exe. Also did a full data wipe before installing the rom.
I noticed some NVRESTORE NV_FAIL_S errors when I changed to new baseband in LGMDP.exe though.. Any ideas? Tried to change 3 times, same errors occur.
Thanks in advance. Sorry for being a noob, but I have been searching for 2 days.
Unfortunately, CM team has removed some frequency from sources and now, with some carrier (eg. Vodafone or 3 IT), data connection doesn't work. I have the same problem. The solutions are:
1. Not use a CM rom
2. Use old baseband with patch for CM.
3. Wait for a fix

[Q] Please Help!!!!

I was on stock GB 2.3.3. then i rooted my phone for the first time today. i was planning to install custom ROM 2.3.4 Phoenix. then i read somewhere that i need to be on the old baseband. and i saw a guide to do that. i did the same.
I purchased ROM Manager. i tried to download ROM. it asked to do a backup, and i did that - within ROM Manager. then it showed me few available ROM's. and i clicked the Mik's CM 7.1 and installed it. but there was no network. Wifi was working.
So, I tried to do a restore. but it said i can't do that because Clkwrkmod Restore is not installed. I installed it using WiFi, but it didn't work saying there was some files missing. then I thought of downloading 2.3.4 Phoenix to overcome this situation, hoping that network will comeback. i downloaded and installed it. but still no network as well as no WiFi.
What should i do now? is baseband an issue here? Pls pls.. anyone help. I know i did some big mistakes..
i will be more than happy to go back to even Froyo 2.2, my original stock ROM. i need to get network working.

Dont use KIES? Why do you even use it?
Save contacts information? Use google contacts.
Sync music? Use doubletwist or manually move music.
Update? Use ODIN.
Somebody should create a thread saying KIES is only good for your device drivers, absolutely useless and anything else.
First of all, what is ODIN? smth like KIES or wut? and second of all i want to upgrade my phone to 2.3.5, simple as that, without installing manually.

Agree
Second if you dont now what odin is and you dont have a update via kies then tour should just wait because if you dont know what you are doing, while flashing with odin you van just as wel go and throw your phone out of a moving car: same chance of making it beter

You dont know what odin is, but still you are using a custom rom? This is why custom roms are not for people who dont know what they are doing...
What you need to do to get kies working again is:
- flash a multi-csc firmware for your area using odin (and make sure it is not a single file firmware)
- change csc-code to match your exact area
- use kies
- dont flash custom roms

please learn first before take further action using custom rom
as optional, you can visit samfirmware for learning flasing rom with odin. you can also find what odin is here

I get the yellow triangle so i guessi rooted properly, ive tried 2 roms, neither will install :9 please help me............ delete this thread after if need be
again, please help
which kernel are you using.. download a custom kernel..like siya or neak.. and make sure its the correct version .. dat is if you are using GB rom then download a GB kernel. the try flashing the rom from recovery
1) Kitchen pro will work only after installing Checkrom,
2) flash another (CWM+Rooting) kerenel from ODIN like siyah,
link for GB Shiyah Kernel : http://gokhanmoral.desean.net/siyahkernel/v2.6/Siyah-v2.6.14.tar (make sure you are on GB version now, otherwise you have to select ICS siyah kernel)

[Q] About which kernel to use

howdy,
I just got this i9100 with the kernel : 2.6.35.7-i9100XWKDD-CL161513 [email protected] #2.
I'd like to put cfroot and clockword etc.. on it but I got a little bit confused.
From what I understand I have to put a newer version kernel on it with similar name "XWKDD".
I tried to find a similar one in the chainfire thread http://forum.xda-developers.com/showthread.php?t=1103399 but i couldnt manage.
So basically my question is which kernel do I use if I want to put a miui or resurrection remix or any 4.1 ROM on it?
Can i just put this Dorimanx one on it via Odin? That seems to work with everything?!
http://forum.xda-developers.com/showthread.php?t=1617219
Also the phone is running stock 2.3.3, rooted but it doesnt have custom recovery.
One more thing if I put another another kernel on it, the I mentioned for example, will it still run the stock Gingerbread?
Thank you in advance
I recommend you to upgrade your phone to ICS, then flash custom kernel and ROM.

Well I tried to update it with Kies, but the bloody thing just crashed on me so I'm pretty afraid of that evil program.
Can I upgrade the official ICS with Odin too?
Also if I do it with Odin is it enough if I only put the ROM on it? Does that update the kernel too (same for the kies if i try again with that, that updates the kernel too?)?
Btw i couldnt find a stock kernel with this code that mine has

Siyah won't work on GB. you can upgrade to stock ICS via Odin. Download a 4.0.3 firmware for your device from sammobile.com and install via Odin. Then flash a custom kernel. For the ROMs you mentioned, siyah is preferable simply since dorimanx has a couple of versions. And determining which version will support which ROM might get a little confusing if you're just starting out. Just my opinion, start off wit siyah, then can switch over to dorimanx later when you figure out which versions support which ROMs.
Good luck. :thumbup:
EDIT: yes, just installing the ROM (firmware) is enough. It'll include the stock ICS kernel along with it.

does it matter which regional ICS i download? I mean, the guy i bought it from said its originally unlocked, but at boot UK O2 pops up /im not using O2 tho so it seems to be true, im just sayin .
Not so much. The only difference between firmwares for different regions is the modem. If after rooting you find your signal isn't as good as it was earlier, you can always flash a different modem at a later stage.
